Readme File / Local Build Instructions

[SamJUK]

Currently, as far as I can tell, there is no README or document that outlines how contribute to the docs / build the project locally.

Whilst its fairly simple to get started if you have used Sphinx before, it adds additional complexity for newcomers to the project/Sphinx to contribute.

Adding a light README file with the following to the repo should help lower the barrier for contribution.

• What this repo contains, and where the end project can be found (Warden Dev Docs at https://docs.warden.dev/)
• What technologies are used to build the docs (Sphinx)
• Local Build Instructions pip install -r requirements.txt && make html && python -m http.server -d _build
